Abstract

The paper presents preliminary results demonstrating the bactericidal properties of surface coatings created on metal and dielectric samples by evaporation of a colloidal solution of nanostructured carbon. A colloidal solution of nanocarbon was obtained using a high-voltage pulsed multi-spark discharge in ethanol with argon injection into the interelectrode space. The main properties of a colloidal solution and the parameters of its constituent nanoparticles are given. Bactericidal activity was assessed by seeding Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) bacterial cultures on prepared slides. Results on suppression of bacterial colonization on samples coated with carbon nanoparticles are presented.
